"Eight thousand years of natural selection in Europe" preprint - updated with Anatolian Neolithic and other data

Eight thousand years of natural selection in Europe

The arrival of farming in Europe around 8,500 years ago necessitated adaptation to new environments, pathogens, diets, and social organizations. While indirect evidence of adaptation can be detected in patterns of genetic variation in present-day people, ancient DNA makes it possible to witness selection directly by analyzing samples from populations before, during and after adaptation events. Here we report the first genome-wide scan for selection using ancient DNA, capitalizing on the largest genome-wide dataset yet assembled: 230 West Eurasians dating to between 6500 and 1000 BCE, including 163 with newly reported data. The new samples include the first genome-wide data from the Anatolian Neolithic culture, who we show were members of the population that was the source of Europe's first farmers, and whose genetic material we extracted by focusing on the DNA-rich petrous bone. We identify genome-wide significant signatures of selection at loci associated with diet, pigmentation and immunity, and two independent episodes of selection on height. [. . .]

Our sample of 26 Anatolian Neolithic individuals represents the first genome-wide ancient DNA data from the eastern Mediterranean. Our success at analyzing such a large number of samples is likely due to the fact that at the Barcin site–the source of 21 of the working samples–we sampled from the cochlea of the petrous bone 9 , which has been shown to increase the amount of DNA obtained by up to two orders of magnitude relative to teeth (the next-most-promising tissue) 3 . Principal component (PCA) and ADMIXTURE 10 analysis, shows that the Anatolian Neolithic samples do not resemble any present-day Near Eastern populations but are shifted towards Europe, clustering with Neolithic European farmers (EEF) from Germany, Hungary, and Spain 7 (Fig. 1b, Extended Data Fig. 2). Further evidence that the Anatolian Neolithic and EEF were related comes from the high frequency (47%; n=15) of Y-chromosome haplogroup G2a typical of ancient EEF samples 7 (Supplementary Data Table 1), and the low F ST (0.005-0.016) between Neolithic Anatolians and EEF (Supplementary Data Table 2). These results support the hypothesis 7 of a common ancestral population of EEF prior to their dispersal along distinct inland/central European and coastal/Mediterranean routes. The EEF are slightly more shifted to Europe in the PCA than are the Anatolian Neolithic (Fig. 1b) and have significantly more admixture from Western hunter-gatherers (WHG), shown by f 4 -statistics (|Z|>6 standard errors from 0) and negative f 3 -statistics (|Z|>4) 11 (Extended Data Table 3). We estimate that the EEF have 7- 11% more WHG admixture than their Anatolian relatives (Extended Data Fig. 2, Supplementary Information section 2).

On the presence of the "East Asian" EDAR variant in Scandinavian hunter-gatherers:
We find a surprise in six Scandinavian hunter-gatherers (SHG) from the Motala site in southern Sweden. In three out of six samples, we observe the haplotype carrying the derived allele of rs3827760 in the EDAR gene (Extended Data Fig. 5), which affects tooth morphology and hair thickness and has been the subject of a selective sweep in East Asia 24 , and today is at high frequency in East Asians and Native Americans. The EDAR derived allele is largely absent in present-day Europe except in Scandinavia, plausibly due to Siberian movements into the region millennia after the date of the Motala samples. The SHG have no evidence of East Asian ancestry 4,7 , suggesting that the EDAR derived allele may not have originated not in East Asians as previously suggested 24 . A second surprise is that, unlike closely related western hunter-gatherers, the Motala samples have predominantly derived pigmentation alleles at SLC45A2 and SLC24A5.
Polygenic selection on height in Europe:

We also tested for selection on complex traits. The best-documented example of this process in humans is height, for which the differences between Northern and Southern Europe have driven by selection 25 . To test for this signal in our data, we used a statistic that tests whether trait-affecting alleles are both highly correlated and more differentiated, compared to randomly sampled alleles 26 . We predicted genetic heights for each population and applied the test to all populations together, as well as to pairs of populations (Fig. 4). Using 180 height-associated SNPs 27 (restricted to 169 where we successfully targeted at least two chromosomes in each population), we detect a significant signal of directional selection on height (p=0.002). Applying this to pairs of populations allows us to detect two independent signals. First, the Iberian Neolithic and Chalcolithic samples show selection for reduced height relative to both the Anatolian Neolithic (p=0.042) and the Central European Early and Middle Neolithic (p=0.003). Second, we detect a signal for increased height in the steppe populations (p=0.030 relative to the Central European Early and Middle Neolithic). These results suggest that the modern South-North gradient in height across Europe is due to both increased steppe ancestry in northern populations, and selection for decreased height in Early Neolithic migrants to southern Europe. We do not observe any other significant signals of polygenetic selection in five other complex traits we tested: body mass index 28 (p=0.20), waist-to-hip ratio 29 (p=0.51), type 2 diabetes 30 (p=0.37), inflammatory bowel disease 21 (p=0.17) and lipid levels 16 (p=0.50).

the dutch are the tallest in europe at country level, though the dinaric alps (which includes a lot of muslims) is the tallest "identifiable" population in europe; think blanka vlasic.

but then, even in a country where 3/4s of the white population speaks dutch they lost for the third time in a row...to the shortest people in europe the spanish...

it should be remembered that for 150 years, spain was the richest and most powerful country on earth.

and the british were the richest and most powerful on earth for about the same length of time, a sesquicentury.

but the british settled sparsely populated areas, areas which they could populate with british, and therefore the anglo-sphere has been in the ascendancy a century later than the apogee of the british empire.

It doesn't matter where EDAR originated. It's the gene that gives East Asians and Native Americans their main *racial* traits, and it was/is present in Scandinavians. Obviously it's related to the non-Caucasoid, Amerindian-like component of ANE that was brought to Scandinavia by H-Gs and again by "Siberian movements into the region millennia after the date of the Motala samples."

This Coudenhouve-Kalergi Plan, which aims to create an amalgamated race in the Old Continent, is no longer secret. Its objective of generating a population with an average IQ of 90 - too stupid to understand, but smart enough to work - is endorsed by Thomas Barnett, American military strategist.

In Ancient DNA, Evidence of Plague Much Earlier Than Previously Known

Bacteria can change history.

In the 14th century, a microbe called Yersinia pestis caused an epidemic of plague known as the Black Death that killed off a third or more of the population of Europe. The long-term shortage of workers that followed helped bring about the end of feudalism.

Historians and microbiologists alike have searched for decades for the origins of plague. Until now, the first clear evidence of Yersinia pestis infection was the Plague of Justinian in the 6th century, which severely weakened the Byzantine Empire.

But in a new study, published on Thursday in the journal Cell, researchers report that the bacterium was infecting people as long as 5,000 years ago.

Exactly what those early outbreaks were like is impossible to know. But the authors of the new study suggest that plague epidemics in the Bronze Age may have opened the doors to waves of migrants in regions decimated by disease.

“To my mind, this leaves little doubt that this has played a major role in those population replacements,” said Eske Willerslev, a co-author of the new study and the director of the Center for GeoGenetics at the University of Copenhagen.

David M. Wagner, a microbial geneticist at Northern Arizona University who was not involved in the study, said that the new research should prompt other scientists to look at mysterious outbreaks in early history, such as the epidemic that devastated Athens during the Peloponnesian War. “It opens up whole new areas of research,” he said.

The new study arose from previous research by Dr. Willerslev and his colleagues. They were able to extract human DNA from101 bones found in Europe and Asia, ranging in age from about 3,000 to 5,000 years old.

As they reported in June, the genetic profiles of people during that 2,000-year period changed with surprising abruptness. About 4,500 years ago, for example, the DNA of Europe’s inhabitants suddenly took on a strong resemblance to that of the Yamnaya, a nomadic people from western Russia.

Wondering what could have triggered such a shift, Dr. Willerslev and his colleagues realized they could test one hypothesis: that epidemics had decimated some populations, allowing new groups to establish themselves.

When researchers search for ancient human genetic material in a piece of bone, they begin by retrieving all the DNA in the sample. Most of it is not human, belonging instead to bacteria and other microbes that colonize bones after death.

Once scientists have gathered all the DNA, they assemble the genetic fragments into larger pieces and try to match them to sequences already identified in earlier research. Normally they set aside microbial DNA to focus on the human material.

Dr. Willerslev and his colleagues wondered if some of the nonhuman DNA they had collected from Bronze Age remains might belong to pathogens. They decided to look for traces of Yersinia pestis, even though the earliest evidence of the infection dates to thousands of years later.

“Plague was just a long shot,” said Dr. Willerslev.

But sometimes long shots pay off. Of 101 Bronze Age individuals, the researchers found Yersinia pestis DNA in seven. Plague DNA was present in teeth recovered from sites stretching from Poland to Siberia.

Early Divergent Strains of Yersinia pestis in Eurasia 5,000 Years Ago

Foley, Marta Mirazón Lahr, Rasmus Nielsen, Kristian Kristiansen, Eske Willerslev

The bacteria Yersinia pestis is the etiological agent of plague and has caused human pandemics with millions of deaths in historic times. How and when it originated remains contentious. Here, we report the oldest direct evidence of Yersinia pestis identified by ancient DNA in human teeth from Asia and Europe dating from 2,800 to 5,000 years ago. By sequencing the genomes, we find that these ancient plague strains are basal to all known Yersinia pestis. We find the origins of the Yersinia pestis lineage to be at least two times older than previous estimates. We also identify a temporal sequence of genetic changes that lead to increased virulence and the emergence of the bubonic plague. Our results show that plague infection was endemic in the human populations of Eurasia at least 3,000 years before any historical recordings of pandemics.

Sardinians: relatively short by design

Behind a pay wall at Nature Genetics:

We report sequencing-based whole-genome association analyses to evaluate the impact of rare and founder variants on stature in 6,307 individuals on the island of Sardinia. We identify two variants with large effects. One variant, which introduces a stop codon in the GHR gene, is relatively frequent in Sardinia (0.87% versus <0.01% elsewhere) and in the homozygous state causes Laron syndrome involving short stature. We find that this variant reduces height in heterozygotes by an average of 4.2 cm (−0.64 s.d.). The other variant, in the imprinted KCNQ1 gene (minor allele frequency (MAF) = 7.7% in Sardinia versus <1% elsewhere) reduces height by an average of 1.83 cm (−0.31 s.d.) when maternally inherited. Additionally, polygenic scores indicate that known height-decreasing alleles are at systematically higher frequencies in Sardinians than would be expected by genetic drift. The findings are consistent with selection for shorter stature in Sardinia and a suggestive human example of the proposed 'island effect' reducing the size of large mammals.


Zoledziewska et al., Height-reducing variants and selection for short stature in Sardinia, Nature Genetics 47, 1352–1356 (2015) doi:10.1038/ng.3403

Also at Nature Genetics...

We report ~17.6 million genetic variants from whole-genome sequencing of 2,120 Sardinians; 22% are absent from previous sequencing-based compilations and are enriched for predicted functional consequences. Furthermore, ~76,000 variants common in our sample (frequency >5%) are rare elsewhere (<0.5% in the 1000 Genomes Project). We assessed the impact of these variants on circulating lipid levels and five inflammatory biomarkers. We observe 14 signals, including 2 major new loci, for lipid levels and 19 signals, including 2 new loci, for inflammatory markers. The new associations would have been missed in analyses based on 1000 Genomes Project data, underlining the advantages of large-scale sequencing in this founder population.
